I agree we don't want to break RDF semantics. The fact that we don't want 
LDP to depend on inferencing doesn't mean we should prevent anyone from 
using it either.

This being said, I think there are ways you can address the monotonicity 
issue and keep membershipPredicate. We could require membershipPredicate 
to be specified rather than have a default value for one, couldn't we?

Let's not jump the gun. I haven't heard anyone say we should ignore the 
issue. I certainly don't plan to! :-)
